BAG-FILLING MACHINE.

Originaly application filed March 20, 1924,!Sera1 No. 700,566. Divided and this application led August `17, 1925. Serial No. 50,721.

illustrated the same as I have embodied f them in a bag filling machine forv handling cement, the present application being a division of my application for LettersPatent liled March `20, 1924, vSerial No. 700,566.

` The main objects of this invention are:

First, to provide an improved rmachine which is automaticin its operation, it only being required that the operator shall place the bags upon the feed spouts; l

Second, to provide an improved bag filling machine of large capacity.`

Objects pertaining to details and econo# mies of constructionand operation of my invention will definitely appear from the dctailed description to follow. j

I accomplish the yobjects of my invention by the devices and means described in the following specification. i The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is clearly illustratedr in the accompanying drawing forming a pait of this application, in which: j Fig. I is a fragmentary'front elevation of a bag filling machine embodying the features of my invention, the machine illustrated being a double unit machine. t

In the drawing similar reference numerals indicatesimilar parts throughout the several views.y n f f Referring to the drawing, I provide a supporting frame designated generallyy by the numeral 1. The details of this form no part of thisinvention, it being understood that itis ofV suoli character as to suitably support the associatedparts. The sti'ucture shown in Fig. Il is a double unitstructuie but as the units are duplicatesa description of one will be sulicient. l

l'Ihematerial is supplied to the hopper 2 by any suitable means. At thebottom of the hopper is an ejector 3 which is fully illustrated, described and claimed in myV above mentioned original application.

The ejector is provided with a discharge opening l having a disk valve 5 pivoted atr 6 and having a discharge opening Z therein f adapted to be brought into register with the y. discharge Llof the feed mechanism. The valve is yautomatically operated by means which will be hereinafter described.

The machine is controlled by a weighing mechanism which in the structure illustrated, comprises a scalebeaiii S pivoted at 9 and provided with a weight 10 and also with an auxiliary weight l11 for accuracy in adjustment, the auxiliary weight being carried by the scale rod 12 mounted on `the scale beam.

Suspended from the scale beam is a platform carrying frame comprising the head piece 13, uprights ll at the ends thereof and a back wall 15 mounted on these uprights, the back wall being curved as'sliown. The A platform 16 is pivoted at 174 so that its forward end may swing downwardly as shown t and provided with springs 22 by means of ywhichy the latches are urged to engaging position. j v y On the under side of the platform is a transversely disposed rod 23 having keepers 24- and 25 with which the latches 19 and 20 engage when the platform` is in erected position. Springs 26 are connected to the frame and to the platform for yieturning the platform to its erected position after a filled bag has been discharged. When the, plat-form moves downwardly the latch 20 comes into Contact with the tripping lug 27 on the adjustable plate 28 carried rby an arm 29 projecting from theframe, thereby disengaging the latch allowing the platform to drop. The rod 23 issupported for limited rotative movement thereby permitting 1t to become disengaged from the latch 19 when :released by the latch 20. The spring 30 returns the rod to proper position to present its keepers 24 and 25 to the latches when the platform `is'returnedl bv the spiings 26.

The scale beam also carries the spout carrier 3l which is pivoted on the inwardly projecting arm 32 oi" the scale beam ift/33. The carrier overlaps and overhangs ,the valve and is provided with a pair of spouts Se: monnted yon the ivots 75 so that t ey may 'swing downwarc to discharge the led bags. These spouts are returned to Ytheir erected position iby .the l,spri'iligs 36 aconnected to the carrier at one' lend Aand to the arms 37 Aon the pivots ,at their other ends.

'The sliding latches 38 are mounted on the carrier by means of vthe slide way 3 9 to engage the bases of the spouts when the sponts are in erected position. the carrier is oscillated the spouts are alternately brought- HtQ resister with the declare@ opening l.

The bags shown at e() are of the valve or ,Self-Cleans tru@ 'especially .designed t0 .11@- ceive the. spouts. bags are retained upon the .spouts by means of the bag holders l1 which are piyoted at t2 on the forwardly projecting arnis d3v and held yieldingly in engaging position by the spring f1.4, 4The `operator pushes the bag under Athe bag holders which are of'such length that a push thereon tends to make ,the jaw grip the bag more firmly.

lVhen, however, the latch 3S is released the spout drops downwardly .thereby r y, z ing tliebag, and this is timed with thereleasing of "the platform soA that the filled bag is' ejected. 'The pperatoi places an thirty has @D a S1191# which is' in l10n-tiling position ythat as seen as the bag ifsvldischarged the( `spouts`v are autoniatically shifted.

'The ycarrier is zliutoniatically shifted or oscillated by means of the actuating lever l5 which pivoted `on ,the l'ameat' and proyided wtth. a roller engaging yin lthe yoke formed in the upper vof the carrie: This .reke uint-idee a )auf .0f Seats 19 oii thel opposite 'sides of theupivot ef the yoke.

This @1.1153 else. Serves yas a lateral Aort for the `carrier 3 which iis provided witlji a boss 55 with which the adJusting screw 56 slidably engages, that is, the screw has a bearing engagement with this boss. -The latches 38 are alternately brought into coacting relation with this trip arm. y

To time the actuation of the .valve with ,theA her parts thevalve actuating lever 57 whic is pivoted at 58 and has ay siot 59 engaging a pin 60 on .the .valve operated from a rockshaft Gl having an arm thercon lengaging.; the cam slot 63 inthe lever The arm 651 on the rockshaft connected to the `weight 10 so that .when the weight moves forwardly under the rod on ,they scale beam, .the arm 62 moves downwardly in the cam slot vactuating the lever 5.7 yto close the valve.

To accelerate or cause quick action of the parts, thereby closing the valve quickly and also ,causing quick movement ofthe connecting parts, provide an Aelectromagnet ,60, the .armature of which,` not illustrated, is connected by the rod 66 to an arm l? on the rockshatt 61. This eleetromagnet is in turn controlled fronrythe switch designated generally by the numeral .68 connected by wires to Ythe electromagnct. 'llie switch illustrated of the mercury type. it,

however, being shown conventionally.

The switch actuating rod 70vr is pivotally connected to the lever 7l kwhich is pivoted at 72 on an arm 73 projecting from the frame. The scale rodlQ4 is provided with a tap'pet 74 adapted to yengage this lever 7l on the downstrole of the rod. orr when the scale beam is ractuated by the weight- -thereon, thereby closing the switchand` actuating the electromagnet as stated to accelerate the movement of the parts'.v The spring 75 yieldingly supports the trip lever 7l and allows the tappet to return to its initial po- Sition as shown in FiglYII.

To lock the carrier in its actuated position, provide a locking dog 76 which is pivoted at 77 and held -yieldingly in engaging position by the coiled spring 78. the enga'ging end 79 of the dog projecting through a hole SO in the frame-piece Sl to engage a recess-like keeper 82 in the carrier. As the carrier moves downwardly this locking dog is disengaged, the lower end of the keeper being inclined or beveled so that the dog.r is pushed rearwardly thereby releasing the carrier for itS Qcillating movement.

These various operations are timed so that all the operator is required to do is to place the on the spouts. As soon as the required weicht 'ot 'material has 'been discharged into the ybag the weight uit thc filled bag actuates' the scale. 'tl'icreby cugaging the spout supportinn` latch. and also lwhen a rpredeterinined point reached the platform is released and the bag discharged.
